123mail settings for other email programs

Use these settings to set up your 123mail mailbox in Thunderbird or any other email program.

Incoming mail (IMAP) Outgoing mail (SMTP)
Server my.123mail.be my.123mail.be
Port 993 465
Encryption SSL/TLS SSL/TLS
Username Your full email address
Password The password of your mailbox (also required for outgoing mail)
Note

Always choose IMAP as account type: your email stays on the server and remains synchronised across all your devices and the webmail.

Tip

Many programs, such as Thunderbird, try to detect the settings automatically. Afterwards, check that the server is my.123mail.be and the encryption is SSL/TLS.
